    Abstract: Disclosed is a sensing device including a guided surface wave receive structure, a physical parameter sensor, and a radio frequency transmitter. The guided surface wave receive structure may be configured to obtain electrical energy from a guided surface wave traveling along a terrestrial medium. The physical parameter sensor may be coupled to the guided surface wave receive structure. The physical parameter sensor may also measure a physical parameter associated with a physical environment local to the physical parameter sensor. The radio frequency transmitter may be coupled to the guided surface wave receive structure and communicatively coupled to the physical parameter sensor. The radio frequency transmitter may also obtain a physical parameter measurement and transmit the physical parameter measurement over a wireless network.

    Abstract: Disclosed are various approaches for determining a location using guided surface waves. A wavelength and a phase of a base guided surface wave launched from a ground station and received by the guided surface wave receive structure are identified. A range of an overlaid guided surface wave launched from the ground station and received by the guided surface wave receive structure are identified., wherein the range of the overlaid guided surface wave is measured as a number of wavelengths of the base guided surface wave. A distance of the guided surface wave receive structure from the ground station based at least in part on the phase of the base guided surface wave and the range of the overlaid guided surface wave is calculated. Finally, a location of the guided surface wave receive structure based at least in part on the distance of the guided surface wave receive structure from the ground station is determined.

    Abstract: Disclosed are various approaches for determining positions of a navigation unit and correcting for errors. The navigation unit can receive a guided surface wave using a guided surface wave receive structure. The navigation unit can then determine a potential location of the guided surface wave receive structure. Finally, the navigation unit can determine an accuracy of the potential location based at least in part on a secondary data source.
